Mying is telling me it'll be ready for it's first one at 16,500 kms. I probably would go by that, but i believe my tires are due for rotations every 10,000 so ill probably just get them both done at the same time.

Dealership told me to go by the Oil Monitor when i asked if i needed it at 5,000.

The factory oil is an ACDelco Dexos 1 synthetic blend. It is only really good for 6,000 miles. Oil testing has been done that shows it's pretty much shot by that point and should probably be changed at even 5,000 miles.

The recommended oils for this car are Dexos 1 approved fully synthetic oils. Oil testing analysis has shown that Mobil 1 consistently does well and even exceeds the 10,000 mile OCI that the OLM may suggest. Some synthetics however will only allow a 7,500 or 8,000 mile OCI. The OCI assumes that you have a high quality fully synthetic oil in your car, which the factory oil (and that which the dealers will change your oil with) is not.

My oil change cycle is 1,500, 6,000, 10,000, and then every 5,000 miles. I balance, rotate, and inspect my tires every 5,000 miles. Actually I pay Discount Tire to rotate and balance the tires but I personally check the tread wear on each tire while it's off the car. I also do a quick visual on the suspension to check for any obvious problems. Discount Tire has a deal that you can pay for the lifetime rotation/balancing even for tires not bought there. Rotating the tires and changing the oil at the same time makes it easy to remember to do.

Has anyone checked the ACDelco Dexos1 oil's life expectancy after the first oil change? The engineers at GM should know what oil will be used at the factory and by their dealerships, so why calibrate the oil life monitor to run well past the life expectency of the factory/dealership oil?

No idea why GM calibrated the OLM that way, but several GM service techs have noted that the oil shouldn't be used past a 6,000 mile interval. I'll be sticking to either Mobil 1, Pennzoil, or Valvoline full synthetic oil and going by the oil life monitor for my car.

I do recall seeing someone's post with an oil analysis of said oil on this board, showing it would certainly not last till the 10,000 mile OCI that the OLM was suggesting.

Yes, your owner's manual also recommends 4.2 quarts of transmission fluid as the total capacity for the automatic transmission, when in reality, the correct capacity is 8.5 quarts and the drain and re-fill amount is 5.8 quarts.

Your owner's manual also recommends a .028 spark plug gap for the 1.4L Turbo, yet the service manual at GM recommends .033-.037, and GM customer support claims the manual is not to be trusted in this case.

Following the owner's manual might get you past the 100k/6 year warranty point. I like to keep my cars a little bit longer.

I really dont understand how any one can run oil 10000 mi. I dont care if the oil is still good and lubricating engine properly at 10000 mi but what are you going to do with contaminants in the oil, like condensation and fuel from the normal combustion process of the engine, Oil and filters are cheap compared to engines. I am changing my oil at 3 to 5000 no matter what oil I decide to use. The oil life monitor cannot really detect oil life, it has set parameters but can not do a oil anaylsis. Just my 2 cents.
